CMBPol Mission Concept Study: Probing Inflation with CMB Polarization
Daniel Baumann, Mark G. Jackson, Peter Adshead +56
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measu…
Gravity Duals of Lifshitz-like Fixed Points
Shamit Kachru, Xiao Liu, Michael Mulligan
We find candidate macroscopic gravity duals for scale-invariant but non-Lorentz invariant fixed points, which do not have particle number as a conserved quantity. We compute two-po…
Holographic Systematics of D-brane Inflation
Daniel Baumann, Anatoly Dymarsky, Shamit Kachru +2
We provide a systematic treatment of possible corrections to the inflaton potential for D-brane inflation in the warped deformed conifold. We consider the D3-brane potential in the…
Stringy Instantons in IIB Brane Systems
Shamit Kachru, Dusan Simic
In this note, we study D-brane instantons which intersect N=1 supersymmetric configurations of space-filling D-branes in general Calabi-Yau compactifications of type IIB string the…
A Gravity Dual of Metastable Dynamical Supersymmetry Breaking
Oliver DeWolfe, Shamit Kachru, Michael Mulligan
Metastable, supersymmetry-breaking configurations can be created in flux geometries by placing antibranes in warped throats. Via gauge/gravity duality, such configurations should h…
